Abstract

A method and apparatus for drying and/or pre-heating in particular scrap metal with the aid of waste gases deriving from an electric arc furnace. The waste-gases are passed from the electric arc furnace through a line (1,2,3) which is arranged between an external, outwardly insulated container (6) and an inner container (4) for accommodating the scrap metal, with a gap (7,8) located between the waste-gas line and the containers. Air is drawn in through the gap (7, 8) and absorbs heat from the wall (3) of the waste-gas line, whereafter the heated air is caused to pass through the scrap (5) in the inner container (4) and to deliver heat to the scrap.
